[kolla][nova][cinder] Got Gateway-Timeout error on VM evacuation if it has volume attached.

Hi everyone, I met an issue when try to evacuate host. The platform is stable/rocky and using kolla-ansible to deploy. And all storage backends are connected to Ceph. Before I try to evacuate host, the source host had about 24 VMs running. When I shutdown the node and execute evacuation, there're few VMs failed. The error code is 504. Strange is those VMs are all attach its own volume. Then I check nova-compute log, a detailed error has pasted at below link; https://pastebin.com/uaE7YrP1 Does anyone have any experience with this? I googled but no enough information about this. Thanks!
